Question

Which category of primates is more ancestral: strepsirrhine or haplorhine?

(A) Strepsirrhine
(B) Haplorhine
(C) Both of the above
(D) None of the above

Answer 1

Strepsirrhine primates are more ancestral than haplorhine primates.

Step-by-step explanation:

The category of primates that is more ancestral is strepsirrhine. Strepsirrhines, also known as the wet-nosed primates, include prosimians like lemurs, bush babies, and pottos. They evolved earlier than the haplorhines and possess anatomical traits that distinguish them from the haplorhines, such as a grooming claw and a toothcomb.
